Breaking through into space travel, humans leaving Earth and defeating gravity, taking steps on the Moon, and various other achievements were pivotal moments in human cultural development. In particular, the scientific and technological advancements stand as an inspiration to the scientific community of students, teachers, and researchers ...

The International Space Station is a platform for scientific research that requires one or more of the unusual conditions present in low Earth orbit (for example microgravity, -radiation and extreme temperatures). The primary fields of research include human research, space medicine, life sciences, physical sciences, astronomy and meteorology.
For example, the meteoroids associated with the Perseid meteor shower travel at an average speed of 58 km/s (130,000 mph; 210,000 km/h). [2] Mechanical damage from debris impacts have been studied through space missions including LDEF, which had over 20,000 documented impacts through its 5.7-year mission. [3]
Space exploration, like its classical form astronomy, is one of the main sources for space science. While the observation of objects in space, known as astronomy , predates reliable recorded history , it was the development of large and relatively efficient rockets during the mid-twentieth century that allowed physical space exploration to ...
Since the early 1990s, research began on the salutogenic (or growth-enhancing) aspects of space travel. One study analyzed the published memoirs of 125 space travelers. [29] After returning from space, the subjects reported higher levels on categories of Universalism (i.e., greater appreciation for other people and nature), Spirituality, and Power.
Artistic view of Deep Space 1, showing both the solar panels and ion engine (with blue exhaust), major aspects of this solar electric design. Solar energy may also be temporarily stored in chemical batteries inside the spacecraft bus. The Dawn spacecraft's xenon tank prior to integration with spacecraft. The xenon was the propellant for the ...
Adequate energy (caloric) intake is a necessary requirement for humans living and working in space, and much attention has been focused on this requirement. Less effort has been spent on understanding how the caloric heat generated by energy expenditure is handled by humans whose physiologic responses to heat may be altered in the unique ...
